PRODUCT DESСRIPTION
DVB-T encoders - modulators MHD001, MHD001P are intended to encode HDMI video and audio signal to DVB-T signal and modulate it in VHF and UHF ranges. MHD001P is packed with external mains power supply.
The modulators are intended for indoor use only. Suitable for moderate and tropical climates.
SAFETY INSTRUCTIONS
Installation of the modulator must be done according IEC60728-11 and national safety standards.
The modulator is powered from external power supply +12 V. This voltage is not dangerous to life.
Any repairs must be done by a qualified personnel.
To avoid the electric shock follow these instructions:
Do not plug mains power supply of the modulator into the mains until all cables have been connected correctly;
To disconnect the modulator from mains completely, disconnect plug of modulator power supply from mains socket;
Modulator shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, shall be placed on it;
Avoid placing modulator next to central heating components, near highly compustible materials and in areas of high humidity;
Before connecting the modulator to multimedia system, be sure that system is installed in accordance to national safety standards;
Devices of multimedia system should have easy access to disconnect them from the mains supply;
No naked flame sources, such as lighted candles, should be placed on modulator;
If the modulator has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before plugging into the mains;
Do not insert any objects into ventilation openings;
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths, curtains;
Mount the modulator on not flammable wall or in not flammable installation box in vertical position with power supply located on the left. The modulator must be fixed with steel screws Ø 3.5-4 mm. The screws are not included in a package; VHF BAND CHANNELS
